More particularly the object of my invention is to provide asmall, conveniently applied, easily locked and inexpensive device for preventing the operation of the clutch pedal so that having applied it with the gears in neutral position it will be practically impossible to drive the car so as to use it for unauthorized joy riding or to steal the car.

More particularly the object of my invention is to provide a sectional collar or chock adapted to be placed and locked about the clutch pedal shank and extending from the pedal to the floor, thus securely preventing the manipulation of the pedal.

A further object is to design a locking device of this character with a clutch shank engaging element hinged to a base or floor engaging element, thus vadapting the appliance to set itself to the various angles of clutch pedals in current use.

My invention also contemplates the provision of means comprising either a pad lock or a contained cylinder lock for securing the clutch pedal chock in operating position.

My invention also comprises the novel details of construction and arrangements of parts, which in their preferred embodiments only are illustrated in the accompanying drawings, in which Figure 1 is a sectional view through the floor of the car showing the clutch pedal with my invention applied.

Figs. 2, 3 and 4 are enlarged end plan and side views, respectively, of the applianc shown in Fig. 1.

Fig. 5 is a side view of a modified type of rclutch pedal lock.

These lugs 6 are adapted to receive between them a perforated ear 8 cast yintegral with the relatively fixed top clamp or chock section 9. This section is provided with perforated lugs 10 spaced to receive a hinge lug 11 on the relatively movable clamp or chock element 12. The two relatively movable chock elements are provided with perforated locking ears 13 adapted to receive a padlock 14 to secure them in closed position.l The meeting faces of the members 9 and 12 `are provided with a longitudinal recess 15 therethrough large enough to receive the stand The ear v the clutch pedal shank the pedal cannot be operated to release the clutch and therefore `it is not practical to -drive the car with the clutch so locked.

In Figs. 5 and 6 I show a modifiedstructure comprising a base 17 integral with the relatively fixed clamp or chock member 19 corresponding to 9,'to which member 19 isv pivotally connected a relatively movable clamp or chock sectionV 2O corresponding to 12, the two sections 19 and 2O being pivotally connected by a rivet hinge pin 21. In this construction the iixed member 19 is provided With a cored chamber 22 to form a keeper for the lock boltv 23, which bolt is mounted to turn in a counter-bored chamber 24 in the movable element 20, the outer end of this chamber being filled With thebarrel of a pin or like, lock 25, the bolty of this lock being in the form of a at pin 26 which is adapted to fit into` a socket 27 in the inner head of the bolt and to turn the bolt With it." In this arrangement the .chock is sition for aV mechanic to 4attempt to open it purpose.

With the only tools whichA vvill serve'the I consider therefore Vthat to all practical purposes the chock cannotbe removed eXcept at a shop Without injuring or breaking the'clutch pedal.

This invention'is not intended to berestricted in scope t0 the specific embodiments shown, but contemplates such modifications as come Within the spirit and scope of the claim.

What I claim as nevv and desire to secure by Letters Patent, is

A device for locking a foot pedal of an automobile comprising an elongated base portion adapted to be disposed at one side of the pedal to be locked, and provided With raised hinge lugs rounded overhead, a sleeve for the pedal comprising hinger` members adaptedto embracethe'clutch pedal, key controlled lock means to fasten said sleeve sections in position about the pedal, a lateral ofset on one of the sleeve members overlying the rounded hingey lugs on said base and having a hinge lug adapted to beinterposed between the base lugs, a pivot' to connect said lugs together With the curved abutting faces of the l.lugs and shoulders concentric with the pivot, said device when applied to the pedal being adapted to prevent its depression tov change its operating position.

' In testimony whereof I affx'my signature.
